the problem is they had good ideas in the expansion but they didn't do enough testing to see what happen on release. The free 1.6 patch unlocked the paid features of the expansion, and broke things as well. It wasn't just people complaining.

It's difficult to "serve a person". But it is far more difficult to bring up "people who serve".

The Europa Universalis series has been a beta test since EU1, really. I remember EU2 being essentially unplayable when it came out due to all the new stuff. EU4 has been a ton of fun especially Ironman with the Cheathappens trainer! They're ironing out small bugs instead of having gigantic game stoppers every time. I just wish they wouldn't break the trainer every time they do a minor patch.
